Title: Combustion method for heating furnace for industrial use
Inventor: TAKEDA HIROSHI
IPC: F23C99/00
Filed: 1987-01-19
Abstract: PURPOSE:To improve the efficiency of heat transferred to a substance to be heated, by a method wherein, in a 2-stage combustion method for a heating furnace for an industrial use, cracked light oil is used as fuel, and the primary air ratio is controlled. CONSTITUTION:Cracked light oil is light oil cut produced by a device which performs cracking, e.g. thermal cracking, visbreaking, caulking, contact cracking, and hydrocracking. The preferable cracked light oil has a boiling point range of 200+ or -50 deg.C-340+ or -40 deg.C, a carbon/hydrogen (C/H) weight ratio of 7.5 or more, and a residual carbon content of 0.5wt.% or less. When 2-stage combustion is effected in a heating furnace by using the cracked light oil, it is important that a primary air ratio is controlled to 5-30%. If the primary air ratio is 5% or less, a smoke amount in exhaust gas from the heating furnace increases; meanwhile, when it exceeds 30%, a radiation factor decreases: therefore, it is not preferable. Further, an atomize air pressure is preferably 0.5-2kg/cm<2>.G.

Title: Manufacture of optical element
Inventor: HIJINO MASAMICHI
IPC: C03B11/00
Filed: 1998-01-20
Abstract: PROBLEM TO BE SOLVED: To provide a manufacturing method of an optical element by which cracks and haze are not generated in an optical element, and also, flows are not generated in the surface of a forming mold. SOLUTION: This manufacturing method comprises: forming, on the surface to be formed of an optical element material, a film which has lower hardness than that of the surface of the forming mold and is removable by at least any one of thermal oxidation or dissolution into a solution; subjecting the optical element material provided with the film to press forming; and thereafter, removing the film by thermal oxidation or dissolution into a solution. Accordingly, cracks and haze can be prevented from being generated in the optical element even when cracks or the like are generated in the surface of the optical element material provided with the film, at the time of subjecting the optical element material to press forming, since the film is removed by thermal oxidation or dissolution into a solution after the press forming.  Also, since the hardness of the film is lower than that of the surface of the forming mold, flaws can be inhibited from being generated in the surface of the forming mold.

The hydrophilic groups and the hydrophobic groups in the liquid deposit on the substrate selectively and preferentially, the substrate has hydrophilic properties and hydrophobic properties and is easy to be wetted by the treating liquid, no bubble remains because of small surface tension, and treatment can be executed uniformly. The substrate is pulled up, the treating liquid is evaporated through decompression, pressure is returned to atmospheric pressure, and the treating liquid on the surface of the substrate is removed by pure water.

Title: Foam jet type burr removing device
Inventor: NAGAYAMA YUKIO
IPC: B26F3/00
Filed: 1987-01-19
Abstract: PURPOSE:To prevent polishing material from biting a workpiece so as to avoid any deterioration of the workpiece even though it is made of a material easily bitten by the polishing material, by removing the burrs on the workpiece through collision of a foam jet with the workpiece. CONSTITUTION:When pressurized fluid is injected from an injection nozzle 8 into liquid (containing polishing material) 7 inside a liquid tank 6, many bubbles are generated in the liquid 7 inside the liquid tank 6 on account of cavitation. On the other hand, the jet stream injected into the liquid 7 inside the liquid tank 6 from the injection nozzle 8 is decelerated by its contact with the liquid, and allowed to descend inside the liquid 7 while being dispersed inside the liquid 7 and to form a circulating flow by reversing its flow direction upward after colliding with the bottom face of the liquid tank 6. Bubbles trapped in the circulating flow are compressed by the descending jet stream to become compressed bubbles. Then, the circulating flow (i.e. foam jet) rushes against a workpiece (semi-conductor reed frame) 3 so that the burrs on the frame 3 are removed by the synergistic effect consisting of the rushing energy and colliding action caused by explosion of compressed bubbles.

Title: Oil coating device for image forming device
Inventor: OGURI SHINICHI
IPC: G03G15/20
Filed: 1987-01-19
Abstract: PURPOSE:To supply sufficient oil and to secure the uniform coating of oil by a fixing roller by forming a gap between adjacent rollers. CONSTITUTION:Oil scooped up by a scooping-up roller 3 forms an oil pool L1 at a position opposite a roller 2, oil is scooped up from this oil pool by the scooping-up roller 2 to form an oil pool L2 at the position where the roller 2 contacts a coating roller 1, and oil is supplied from this oil pool L2 to a fixing roller 5 by the coating roller 1. The gap S is left between the scooping-up rollers 2 and 3, so a large amount of oil stays at this part. The scooping-up roller 2, therefore, form the oil pool L2 of a sufficient amount of oil at the abutting position where the roller L1 abuts on the coating roller 1. Consequently, a uniform oil film is formed on the surface of the coating roller.

Title: Combustion cylinder connection structure of gas turbine engine
Inventor: TAKAMURA TOUSAKU
IPC: F23R3/42
Filed: 1991-01-28
Abstract: PURPOSE:To reduce an outer diameter size and enable a member to be formed with ceramics by connecting a bent inlet duct to an outlet of a combustion cylinder and allowing the same to penetrate a plenum outer wall, and disposing in the plenum the outlet for combustion gas such that the combustion gas outlet approaches the circumferential direction and axis of the plenum. CONSTITUTION:An inlet duct is mounted, penetrating the outside of an outlet duct 2 penetration part of a plenum 1 outer wall. The inlet duct 5 is shaped into an elbow, and a flange outer surface of a combustion gas inlet 5a is joinned with a penetration hole peripheral edge of the plenum 1, and a combustion gas inlet 5b is disposed toward the periphery of the plenum 1, and further a combustion gas outlet of a combustion cylinder 6 is joinned with the flange of the combustion gas inlet 5a. Hereby, a combustion gas flow rate is reduced and hence the outer periphery size of the inlet duct 5 is reduced. Thus, the outer diameter size of the inlet duct 5 to which the combustion cylinder 6 is connected is shortened. Since the combustion gas flows out circumferentially of the plenum 1, a turbine efficiency is raised, and since the combustion cylinder 6 and the inlet duct 5 are mounted through a spring, the strength is increased to promote the construction of the device with ceramics.

Title: Memory cell
Inventor: SASAKI TORU
IPC: G11C11/41
Filed: 1986-01-21
Abstract: PURPOSE:To attain high-speed access without making the constitution large in size by reading binary information stored in a storage means without forming a current path between a storage means and a bit line. CONSTITUTION:Voltage information is written differential on a bistable circuit 9 by using bit lines BL1, BL2 at the write. Thus, the voltage information is written surely and stably without making inverter circuits 5, 7 constituting the circuit 9 asymmetrical. The bit lines BL2, BL3 are brought respectively to H and L levels in advance at the reading to bring word lines WL2, WL3 respectively to the H and L levels, then a current flows from the line BL2 to an input/output terminal B of the circuit 9. Thus, the line BL2 goes to the L level and the voltage information at the terminal B is read via the line BL2. Further, a current flows from the voltage source to the bit line BL3 via MOS transistors TRs 31, 33. Thus, the inverted information of the voltage information at the terminal B is read via the line BL3.

Silanol which is being dissolved in ethanol, is coated with a rotating-coating method and the coating layer is baked at about 180 deg.C. Thereafter, the coating layer is sintered by a heating process at 450 deg.C or higher to change to a silicon oxide film. In this way, the insulator layer 9 with a taper form is formed. Thereafter, boron B being P type impurity is ion-implanted to form an ion-implanted layer 10. This dose amount is decreased gradually in the directions of the edges of the opening in the SiO2 film 2. Next, a P type base area 4 is formed so that a cross-section form of the collector-base junction 6 can have a larger curvature radius at bending sections 7, 8.
